Check the LEDs

CISCO PIX 501

F I R E W A L L

The LINK/ACT LED indicators on the front panel of the PIX 501 are normally solid green when a

link is established and flashing green when the ports are active. Each inside Ethernet interface

(1 through 4) has two LEDs to indicate the operating speed and that the physical link is established.

Note If all LEDs are operating as expected (see Table 1), this concludes the PIX 501

installation. The pages that follow include additional optional procedures.

Description

The device is powered on.

The device is powered off.

Network activity, such as Internet access, is present.

The correct cable is in use, and the connected equipment has power.

No link is established.

Tip If the LINK/ACT LED does not light up, you might be

using the wrong type of cable. Try replacing the yellow

(straight-through) Ethernet cable with the orange (crossover)

Ethernet cable.

One or more IKE/IPSec VPN tunnels are active.

No VPN tunnels are active. If the default configuration has not been

modified to support IKE/IPSec VPN tunnels, the LED does not light up

because it is disabled by default. Also, the LED does not light up when

PPTP/L2TP tunnels are established.

The interface is enabled at 100-Mbps half or full duplex

(autonegotiated).

The interface is enabled at 10-Mbps half or full duplex.
